Electro Statistics
- Coulomb’s Law: Coulomb’s law states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. Mathematically, it can be expressed as F = (k * q1 * q2) / r^2, where F is the electrostatic force, q1 and q2 are the charges, r is the distance between them, and k is the electrostatic constant.
- Electric Field: The electric field at a point in space is the force experienced by a unit positive charge placed at that point. The electric field is a vector quantity, and its direction is the direction in which a positive test charge would move if placed in the field. The electric field due to a point charge is given by E = (k * q) / r^2.
- Electric Potential: Electric potential at a point is the work done in bringing a unit positive charge from infinity to that point. It is a scalar quantity and is measured in volts (V). The electric potential due to a point charge is given by V = (k * q) / r.
- Electric Potential Energy: The electric potential energy of a system of charges is the work done in assembling the charges in that particular configuration. The electric potential energy of two point charges is given by U = (k * q1 * q2) / r.
- Capacitance: Capacitance is the ability of a conductor to store charge. It is defined as the ratio of the magnitude of the charge on one conductor to the potential difference between the two conductors. The capacitance of a parallel plate capacitor is given by C = (ε₀ * A) / d, where C is the capacitance, ε₀ is the permittivity of free space, A is the area of the plates, and d is the distance between them.
- Ohm’s Law: Ohm’s law relates the current passing through a conductor to the potential difference across its ends and the resistance of the conductor. It states that the current (I) flowing through a conductor is directly proportional to the potential difference (V) across its ends and inversely proportional to the resistance (R) of the conductor. Mathematically, it can be expressed as V = I * R.
- Kirchhoff’s Laws: Kirchhoff’s laws are used to analyze complex electrical circuits.
- Kirchhoff’s first law (or the law of conservation of charge) states that the sum of currents entering a junction is equal to the sum of currents leaving that junction.
- Kirchhoff’s second law (or the loop rule) states that the algebraic sum of the potential differences in any closed loop of a network is equal to zero.
These are the key topics related to electrostatics in the NEET physics syllabus. Make sure to practice numerical problems and understand the concepts thoroughly to perform well in the exam.

Case Study on NEET PHYSICS SYLLABUS Electro Statistics
Electrostatics in Air Pollution Control
Introduction: Electrostatics plays a crucial role in various applications, one of which is air pollution control. In this case study, we will explore how electrostatics is utilized to control air pollution, specifically in the removal of particulate matter from industrial emissions.
Background: Industrial processes often release particulate matter into the atmosphere, which can have adverse effects on human health and the environment. Particulate matter includes tiny particles such as dust, soot, and aerosols. To mitigate the impact of these emissions, electrostatic precipitators (ESP) are widely employed.
Electrostatic Precipitators (ESP): An electrostatic precipitator is a device that utilizes electrostatic forces to remove particulate matter from industrial flue gases before they are released into the environment. ESPs are commonly used in power plants, cement factories, steel mills, and other industrial settings.
Working Principle: The working principle of an ESP involves three main steps: ionization, migration, and collection.
- Ionization: The flue gas containing particulate matter is passed through an ionization section in the ESP. In this section, high voltage electrodes apply a strong electric field to the gas. This electric field ionizes the gas molecules, creating positive ions and negative ions.
- Migration: Once the gas is ionized, the charged particles (both positive and negative ions) are subjected to an electric field that is established between a series of high voltage electrodes called the charging section. The electric field causes the charged particles to migrate towards oppositely charged collection electrodes.
- Collection: The charged particles, now being attracted to the collection electrodes, deposit on the surface of these electrodes. The collected particles form a layer known as the “precipitate” or “cake.” Periodically, this precipitate is removed from the collection electrodes through mechanical means such as rapping or flushing, ensuring continuous operation of the ESP.
Benefits and Advantages: Electrostatic precipitators offer several benefits for air pollution control:
- High efficiency: ESPs can effectively remove particulate matter, including both large and small particles, with high efficiency, typically above 99%.
- Versatility: ESPs can handle a wide range of particulate matter sizes and types, making them suitable for various industries and applications.
- Low energy consumption: Compared to other air pollution control devices, ESPs generally consume less energy, contributing to cost savings and environmental sustainability.
- Compliance with regulations: ESPs help industries comply with air quality regulations and emission standards set by environmental authorities.
Conclusion: Electrostatics, specifically electrostatic precipitators, have proven to be a reliable and efficient technology for controlling air pollution caused by particulate matter emissions in industrial processes. By utilizing the principles of electrostatics, ESPs play a vital role in minimizing the environmental impact of industrial activities and ensuring cleaner air for communities.
